One event has a sack with mice or ants that bite. You can get a head start on healers if you ... believe it or not ... drop the KIDS on a person who is sick from the bites, they will heal someone and they will gain some healing knowledge on their meters!!!! ALSO ... when someone is sick, drop ANY villager on them and they will not start kissing ... they too will heal the person, and they don't even have to be set on Healing to do so!!! (personally, I think it is good for everyone to have a little healing knowledge!!!)
